A moderately active 40-pound dog needs an average of 1,434 calories per day. Taryn's dog participated in a dog race this morning, so it will need more than the average calories. Taryn's dog has already eaten 717 calories, and she feeds her dog 239 calories per meal.

       239x + 717 > 1,434

How many more meals does Taryn need to feed her dog today?

  A. 
x > 239
  B. 
x > 717
  C. 
x > 3
  D. 
x > 4

Following the basic rules of algebra, we can place all numerical values to one side.
$$x > \frac{ 1434 - 717 }{ 239 } ~~\rightarrow~ ~?$$
Tip: Plug this into a calculator to find the actual value.

1434-717 is 717 but what would I do with the bottom, divide it?

anonymous · Answer

So then x would equal 3
